Header or No Header?

I am having a poll at the moment. I have just finished redesigning my blog after being inspired by Beth from Bethany's Cave.

I came up with a slight problem though, to have a blog header or not. I have made one which does look good, but I can't decided whether it looks better with it or with out.

If needs be I am willing to make another, better header, but let's see what it looks like first!

with header

without

Please leave your view! Whether to make a different one or not have one at all. Please be truthful. Thanks!
